"Brazil has done more than any other country over the past five years to cut global warming emissions by dramatically reducing its deforestation. Destroying tropical forests is responsible for about 15 percent of global warming pollution, and Brazil had been the biggest source of deforestation pollution. Its reduction is a stunning turnaround.

This method may potentially be suitable for designing novel light sources resembling lasers that work in the x-ray range. Among other applications, they might allow building more powerful computer chips.

Researchers are creating a system that harvests heat from an engine's exhaust to generate electricity, reducing a car's fuel consumption.

some researchers at the MIT Media Lab are aiming to put the controls back in people's hands, in a way that provides sophisticated and continuous control and could slash lighting bills by more than half.

Large quantities of antihydrogen atoms were first made at CERN eight years ago by two other teams. Although they made antimatter they couldn't store it, because the anti-atoms touched the ordinary-matter walls of the experiments within millionths of a second after forming and were instantly annihilated-completely destroyed by conversion to energy and other particles.

Professor Andre Geim, who along with his colleague Professor Kostya Novoselov won the 2010 Nobel Prize for graphene - the world's thinnest material, has now modified it to make fluorographene - a one-molecule-thick material chemically similar to Teflon. Fluorographene is fully-fluorinated graphene and is basically a two-dimensional version of Teflon, showing similar properties including chemical inertness and thermal stability.
